Download: Google Earth 5 w/Mars
An early overview is available here. This is exactly what I've been waiting for ever since Google Earth came out five years ago. And HiRISE integration is amazing. |

Newbie here. I usually just hover around these forums like a ghost, but I thought I'd share some of the stuff I've figured out about Google Mars.
I was trying to get the waypoints to work so that the label appeared only when you hovered over the icon, like in the "official" waypoints that take us through conjunction. It turns out that this is not permitted by the UI, but I dove into the XML and was able to figure it out. Basically you need to define a "styleMap" the contains two styles, keyed on "normal" and "highlight", and then set the placemark's "styleUrl" element to the map instead of the style. The key is that the "scale" should be zero for the "normal" style, and non-zero for the highlighted. Note that the "description" tag is necessary for the hover event to fire (and the label to show). The attached file demonstrates this. It is a seamless extension of the Opportunity route map provided in Google Mars and picks up where that one leaves off. It includes the traverse path, waypoints, and local place names in the same format and structure that has already been established, updated through Sol 1795. oppy_traverse_2009.kml ( 6.37K ) Number of downloads: 658 It's actually pretty simple, but it will probably require that further updates be made in the XML instead of the application UI. Hopefully Google will surface style maps in a future release of the product. There's a pretty decent reference guide to the KML syntax here: http://code.google.com/apis/kml/documentat...lreference.html Poolio |
